Abstract :
This article considers window-based congestion control of network with single TCP flow. Based on recently developed linearized fluid-flow model of TCP behavior, the robust stability of network against round-trip time delay is analyzed and the corresponding controller is designed using LMI approach. Simulation results present a new TCP protocol structure in which a local feedback at TCP source is formed so that the network can tolerate a larger maximum round-trip time delay.
